Which of these fruits are not berries: strawberry, blackberry, banana, tomato, and blueberry? Turns out just two of them aren’t: the strawberry and the blackberry. As it turns out, a berry is any fruit that grows from one flower and has just one “ovary” to hold seeds. In the case of a strawberry, it has lots of ovaries and each one holds one seed — those yellow dots all around the outside. Meanwhile, tomatoes, avocados, bananas and pumpkins are berries. We hardly think of tomatoes or pumpkins as being fruits at all, much less berries, but they grow from flowers according to the rules. Blackberries and raspberries mix things up even more: each of them is an “aggregation” (cluster or clump) of “drupelets,” the name for each little juicy ball, each of which holds one seed. So as berry season winds down, don’t be sad — if you’re missing berries, just nibble on some bananas and tomatoes.

Wee ones: If you nibble on a blackberry, a tomato, a banana and a blueberry, how many real berries are you nibbling?

Little kids: A strawberry has about 200 seeds on the outside! If you bite off 1/2 of them, how many seeds are left?  Bonus: How many seeds are on 10 strawberries?

Big kids: If you eat a raspberry that has 37 drupelets and a blackberry with 54 drupelets, how many more drupelets does the blackberry have?  Bonus: If you eat 10 of each, how many juicy drupelets do they have altogether?

The sky’s the limit: If you have a handful of raspberries, each with 36 drupelets, and strawberries each with 200 seeds, and the number of strawberries is 1/5 the number of raspberries and there are 80 more seeds than drupelets, how many of each do you have?

Answers:

Wee ones: 3 real berries.

Little kids: 100 seeds.  Bonus: 2,000 seeds.

Big kids: 17 more drupelets.  Bonus: 910 drupelets.

The sky’s the limit: You have 4 strawberries and 20 raspberries. To solve with algebra, if there are s strawberries and r raspberries:

5s = r (relation between number of each)

200s = 36r + 80

Substituting 5s for r, we get

200s = 36 (5s) + 80

200s = 180s + 80

20s = 80

s = 4

That gives us 4 strawberries and 5 times that many raspberries (20). To check, the 20 raspberries will have 720 drupelets, and the strawberries will have 800 seeds, which is 80 more.

Explanation:

synovial joints are characterized by the presence of a joint cavity. the walls of this space are formed by the articular capsule, a fibrous connective tissue structure that is attached to each bone just outside the area of the bone’s articulating surface. the bones of the joint articulate with each other within the joint cavity.

friction between the bones at a synovial joint is prevented by the presence of the articular cartilage, a thin layer of hyaline cartilage that covers the entire articulating surface of each bone. however, unlike at a cartilaginous joint, the articular cartilages of each bone are not continuous with each other. instead, the articular cartilage acts like a teflon® coating over the bone surface, allowing the articulating bones to move smoothly against each other without damaging the underlying bone tissue. lining the inner surface of the articular capsule is a thin synovial membrane. the cells of this membrane secrete synovial fluid (synovia = “a thick fluid”), a thick, slimy fluid that provides lubrication to further reduce friction between the bones of the joint. this fluid also provides nourishment to the articular cartilage, which does not contain blood vessels. the ability of the bones to move smoothly against each other within the joint cavity, and the freedom of joint movement this provides, means that each synovial joint is functionally classified as a diarthrosis.

outside of their articulating surfaces, the bones are connected together by ligaments, which are strong bands of fibrous connective tissue. these strengthen and support the joint by anchoring the bones together and preventing their separation. ligaments allow for normal movements at a joint, but limit the range of these motions, thus preventing excessive or abnormal joint movements. ligaments are classified based on their relationship to the fibrous articular capsule. an extrinsic ligament is located outside of the articular capsule, an intrinsic ligament is fused to or incorporated into the wall of the articular capsule, and an intracapsular ligament is located inside of the articular capsule.

at many synovial joints, additional support is provided by the muscles and their tendons that act across the joint. a tendon is the dense connective tissue structure that attaches a muscle to bone. as forces acting on a joint increase, the body will automatically increase the overall strength of contraction of the muscles crossing that joint, thus allowing the muscle and its tendon to serve as a “dynamic ligament” to resist forces and support the joint. this type of indirect support by muscles is very important at the shoulder joint, for example, where the ligaments are relatively weak.

additional structures associated with synovial joints

a few synovial joints of the body have a fibrocartilage structure located between the articulating bones. this is called an articular disc, which is generally small and oval-shaped, or a meniscus, which is larger and c-shaped. these structures can serve several functions, depending on the specific joint. in some places, an articular disc may act to strongly unite the bones of the joint to each other. examples of this include the articular discs found at the sternoclavicular joint or between the distal ends of the radius and ulna bones. at other synovial joints, the disc can provide shock absorption and cushioning between the bones, which is the function of each meniscus within the knee joint. finally, an articular disc can serve to smooth the movements between the articulating bones, as seen at the temporomandibular joint. some synovial joints also have a fat pad, which can serve as a cushion between the bones.

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
