Answers
Answer:
A. Simple squamous epithelia are found in capillaries, alveoli, glomeruli, and other tissues where rapid diffusion is required.
B. The unicellular glands are scattered single cells, such as goblet cells, found in the mucous membranes of the small and large intestine. The multicellular exocrine glands known as serous glands develop from simple epithelium to form a secretory surface that secretes directly into an inner cavity.
C. The importance of chlorenchyma is that it is the seat of photosynthesis or manufacture of organic food. The importance of aerenchyma is that it has large air cavities which store gases and provide buoyancy to aquatic plants
D. Striated muscles are attached to bones and help in the movement of body parts. So, they are called skeletal muscles.
E. The chloroplast is located throughout the cytoplasm of the cells of plant leaves and other parts depending on the type of plant. Actually, you can see where in a plant the chloroplasts are because chloroplasts are what make the plant appear green. Therefore wherever there is green on a plant there are chloroplasts.
