
2.
Rough appearance because it has
ribosomes
Function: helps make proteins, that’s why it
has ribosomes
Smooth ER:


NO ribosomes
Function: makes fats or lipids

Found outside the cell membrane in plant
cells
What Cell Look Like
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
chromosomes
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 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.
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.
