1.The correct option is

Option A. cell.

A cell is a basic unit of structure and function in living organisms. The cell is a crucial element as it is the structural and functional unit of every organism. Prokaryotes and eukaryotes both are made up of cells they are involved in metabolism, communication, cell division, and many other vital functions important for living.

2.The correct option is

Option D. organs.

A specific type of cell makes up the tissue like blood cells makes up the cardiac muscle tissue. Then different tissues form an organ-like cardiac muscle that forms the heart. This organ is a part of an organ system like the heart is a part of the circulatory system.

3. The correct option is

Option  B. molecules and cells.

The body follows a certain level of arrangement. The atom is the smallest unit that combines to form a particular molecule.

Then different molecules join to form a cell. Although prokaryotic and eukaryotic cells differ in structure and functions.

4.The correct option is

Option D. tissue.

Tissue is a group of specifically designed cells, which in turn forms an organ. These groups of specialized cells work together to perform a specific function. For example, the nerve cells or the neurons work together to carry the message to the human brain in the organisms.

5.The correct option is

Option A. Mitochondria.

It is called the powerhouse of the cell as it carries out cellular respiration to generate energy. It is found in eukaryotic organisms. It converts glucose molecules into energy in the form of ATP.

6. The correct option is

Option C. Vacuole: stores food, water, nutrients, and waste.

The vacuole is a membrane-bound organelle, in the animal cell, they are small in size as compared to plant cells. In-plant they help in maintaining water balance, stores food and nutrients, and also waste products.

7.The correct option is

Option B. Organelle A is chloroplast, Organelle B is vacuole.

Chloroplast is present in plant cells whereas they are absent in animal cells. In-plant cells chloroplast are able to make their own food by the process of photosynthesis, on the other hand, the animal cannot make their own food as they lack chloroplast.

Vacuoles in the plant are big in size as compared to animal cells. They are storage houses as they store water, nutrients and waste.

8. The correct option is

Option B. The cell will lose its shape and support.

The cell wall is an important organelle of plant cells, if the plant cell wall is absent then the cell will lose its shape and support. Diffusion of substance will not take place and due to turgor pressure, the cell will burst and die.

Answer No 1:

The correct option is A. Cell  is the basic unit of structure and function in living organisms.

In biology, a cell can be described as a tiny structure containing organelles, cytoplasm and cell membrane. All the metabolic processes which are important to keep any organism alive occur in the cytoplasm. Hence, cells are known to be the basic unit of structure and function. All cells are specialized to perform different functions. The shape of a cell may vary according to the function it is entitled to perform.

Answer no 2:

The correct option is D. Organs

Particular type of cells in the body work together to make tissues. For example, Bone cells make bone tissues.

Different type of tissues work together to form an organ. For example, cardiac muscles are involved in the forming of the heart.

Different organs will work together to make organ system and different organ systems combined form a whole organism.

Answer No 3:

The correct option is B. Molecules and cells are the two levels of organization just after atoms.

Atoms combined together form molecules. Atoms are the smallest unit of elements which will join to form a particular molecule. Different molecules will join together to form a cell. Cell is the basic unit of life. Mostly, on a broader level, scientists classify cells into plant cells and animal cells. However, plant cells may have different types as well as animal cells may also have different types.

Answer No 4:

The correct option is D. Tissue

Different type of cells work together to make a tissue.

Every cell in an organism's body is specialized to perform different tasks. When specialized cells will work together to perform a task, then these cells will become tissues. For example, different type of muscle cells will make up the muscle tissues.

Answer No 5:

The correct option is A. Mitochondria

A mitochondria can be be described as an organelle having a double membrane and is known to be the power house of a cell. Is is called so because mitochondria is the site where the process of cellular respiration occurs. In this process, a cells converts sugar and oxygen into carbon dioxide and water.Energy in the form of ATP is released during this process. This energy is used by each cell to carry out its functions.

Answer No 6:

The correct option is C. Vacuole: stores food, water, nutrients, and waste

The correct option is C because vacuoles are know to be the storage house of a cell. Vacuoles might store food or any essential nutrients which are necessary for a cell. Vacuoles are present in both the animal and the plant cells. However, in plants cells vacuoles are bigger and present in the center of a cell. In animal cells, the vacuoles are smaller and present on a side. The waste of a cell is also accumulated in the vacuoles.

Answer No 7:

The correct option is B. Organelle A is chloroplast, Organelle B is vacuole

Chloroplast can be described as organelles which are present in the plant cells and eukaryotic algae. They are absent in the animal cells. Due to chloroplast, plants are able to make their own food by a process known as photosynthesis. Animals lack chloroplast and hence cannot carry out the process of photosynthesis to make their own food.

Vacuole is an organelle which is present in both the animal and plant cells. It is known to be the storage house of the cell as it stores food, water and waste of a cell. In plant cells, the vacuole is bigger and is present in the center of a cell. In animal cells, the vacuole is smaller and present at a side.

Answer No 8:

The correct option is B. The cell will lose its shape and support.

Cell wall can be described as extra membrane which is present in the plant cells but absent in the animal cells. The main function of the cell wall is to provide support and protection to a cell. If a cell wall wasn't present, then the plant cell will collapse and lose shape. Hence, B is the correct option.

its like this, "if i give a plant an unlimited amount of sunlight,then the plant will grow to its largest possible size."

hope it let me know if it does or doesn't =^-^=
