Write the structure and functions of mitochondria plastics and vacuoles
Answers
1) Structure of Mitochondria:
They are made of two membranes. The outer membrane covers the organelle and contains it like a skin. The inner membrane folds over many times and creates layered structures called cristae. The fluid contained in the mitochondria is called the matrix.
FUNCTION:
Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. The biochemical processes of the cell are known as cellular respiration.
2) Structure of Plastids:
The plastid is a membrane-bound organelle found in the cells of plants, algae, and some other eukaryotic organisms. ... They often contain pigments used in photosynthesis, and the types of pigments in a plastid determine the cell's color.
FUNCTION:
Plastids are the site of manufacture and storage of important chemical compounds used by the cells of autotrophic eukaryotes. They often contain pigments used in photosynthesis, and the types of pigments in a plastid determine the cell's color.
3) STRUCTURE OF VACUOLES:
Vacuoles are membrane-bound sacs within the cytoplasm of a cell that function in several different ways. In mature plant cells, vacuoles tend to be very large and are extremely important in providing structural support, as well as serving functions such as storage, waste disposal, protection, and growth.
