What Cell Look Like

What Cell Look Like

The cell is the basic unit of life. Cell walls and chloroplasts are found

The cell is the basic unit of life. Cell walls and chloroplasts are found in plant cells only. • The cell wall is a stiff covering outside the cell membrane of a plant cell. • Chloroplast is a green structure in a plant cell where food is produced. It is green because it contains the green pigment chlorophyll.

Both plant and animal cells contain: nucleus cytoplasm transport system vacuoles cell membrane mitochondria

Both plant and animal cells contain: nucleus cytoplasm transport system vacuoles cell membrane mitochondria chromosomes

The nucleus is the control center of the cell. It controls all cell activity.

The nucleus is the control center of the cell. It controls all cell activity. The Nucleus contains chromosomes or the cell blueprints

• The cell membrane is the outer covering of an animal cell. It

• The cell membrane is the outer covering of an animal cell. It gives the cell its shape. • Most of the cells life activities take place within the cytoplasm. The mitochondrion is the powerhouse of the cell. It is a rod-shaped structure that releases energy.

Respiration is the process of releasing energy in sugar that occurs in the mitochondria.

Respiration is the process of releasing energy in sugar that occurs in the mitochondria. Vacuoles are sac like storage spaces in both plant and animal cells. These are larger in plants than in animals. Photosynthesis only happens in plants (producers). This is where they use sunlight to make food.
