Biology Chapter 7.2 Organelles that release and capture energy

cell membrane

A cell structure that controls which substances can enter or leave the cell.

chlorophyll

A green pigment located within the chloroplasts of plants. Can participate directly in the light reactions, which convert solar energy to chemical energy.

cell wall

A rigid structure that surrounds the cell membrane and provides support to the cell

chloroplasts

A structure in the cells of plants and some other organisms that captures energy from sunlight and uses it to produce food.

Inner and outer membrane of mitochondria

Inner membrane is much larger than the outer one The inner membrane is folded up inside the membrane

photosynthesis

Plants and other single-celled organisms capture the energy of sunlight directly for storage and later use

mitochondria

changes chemical energy stored in food into compounds that are easier for the cell to use. Surrounded by outer membrane and inner membrane

What process do chloroplasts use ?

photosynthesis

mitochondrion

Cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use

How do chloroplasts turn energy into food?

Take energy from sunlight and change it into energy stored in food

lipid bilayer

a flexible double-layered sheet that makes up the cell membrane and forms a barrier between the cell wall and it's surroundings

selective permeability

a process in which a membrane allows some molecules to pass through while keeping others out
