2. Cellular functions
Take in what is
needed and get rid of
waster.
Proteins control every
cell function.
For daily life and
growth
For growth,
reproduction and
repair.
Tansport materials,
maintain homeostasis
Make energy
Make proteins
Build more cells

3. Cellular nutrition
and energy
production

4. Cellular respiration
Plants and animal cells need energy to
survive. This happens through cellular
respiration, a series of chemical reactions
to gradually extract energy (ATP) from
glucose.
Glucose + Oxygen = Carbon Dioxide + Water + Energy

5. Cellular respiration
In photosynthesis, plants use
sunlight to produce glucose from
carbon dioxide and water.
Cellular respiration is the process by
which cells break down glucose to
release energy.
During cellular respiration, glucose is
broken down into smaller molecules.
This process releases energy that
cells use to carry out their functions.

7. Nutrition and the cellular membrane
The wall that surrounds the cell is
referred to as the “cellular membrane”.
This serves as a filter through which
nutrient can enter by endocytosis, and
wastes can be excreted by exocytosis.
Transport of nutrient and food can
happen actively or passively.

8. Mitosis
Cellular reproduction through mitosis

9. This is a type of cell división in which one cell (the mother) divides to produce
two new cells (the daughters) that are genetically identical to itself. In this
process, the DNA of the cell’s nucleus is split into two equal sets of
chromosomes.
