1. these contain chloroplasts to catch sunlight a-leaf cells b-root cells ///2.blood is considered a (n) a-tissue b-organ system which one is correct answer and i need explanations

1. A. Leaf cells; 2. A. Tissue.

Step-by-step explanation:

1. Leaf cellscontain the chloroplasts. They are usually thin, so the sunlight can reach the chloroplasts easily. It wouldn’t make much sense for the plant to have chloroplasts in the roots, because the sunlight doesn't reach underground.

2. Blood is a tissue. A tissue is a group of many similar cells (however, blood has both red and white cells) that works together to perform a specific function. An organ is formed from different tissues. An organ system is a group of organs that works together to perform one or more functions.

i'm wiling to try and you : )
