Do interior components found in organisms that you have studied exist in every type of plant and animal
cells? Which components are only found in plant cells and which components are only found in animal cells?
Nucleolus
1.3.2 Plant Cells and Animal cells
Nuclear Membrane Central Vacuole

Plant cells consist of cell wall
which is mostly made up of cellulose that
surrounds the cell membrane. Within Ribosomes
protoplasm, there are cytoplasm and Golgi Complex
organelles that have specific functions, Nucleus
e.g. nucleus and mitochondria – energy Cytoplasm
structures of cells, chloroplasts – interior
structures that contain chlorophylls used in Chloroplast
photosynthesis, and, moreover, vacuoles
that collect water or other substances like Cell Membrane
coloured-substances, starch granules and
nutrients. Cell Wall

Ribosomes

Golgi Complex Animal cells do not have cell wall
but still have cell membrane that
Mitochondrion
surrounds their protoplasm. However,
they have some similar components and
Cytoplasm structures that are found in plant cells, such as
cytoplasm and other organelles like nuclei
Cell Membrane
and mitochondria, but without chloroplasts.

Project Plant and Animal Cells Models
IDEA Groups of students design models of plant and animal cells out of leftovers and present
their works in an invention projects contest.
