Study Notes
Cell Membrane
- The cell membrane is a layer in both plant and animal cells.
- It helps keep fluids and organelles inside the cell.
- It acts as a "security guard" for the cell.
- The cell membrane has small holes that allow certain molecules to enter the cell and prevents harmful molecules from entering.
Cell Wall
- The cell wall is the outer layer of plant cells.
- It helps protect everything inside the cell.
- The cell wall is made of strong materials that keep harmful substances outside the cell.
Cytoplasm
- Cytoplasm is the fluid that fills a cell.
- It’s present in both plant and animal cells.
- Cytoplasm is made up of dissolved molecules that are used in various cellular processes.
Nucleus
- The nucleus is the "control center" of plant and animal cells.
- It controls growth and reproduction.
- It is located near the center of the cell and contains the cell's chromosomes.
Nucleolus
- The nucleolus is a structure found inside the nucleus of both plant and animal cells.
- It is made up of RNA and protein.
- It looks like a nucleus inside a nucleus.
Chloroplast
- Chloroplast converts light energy from the sun into sugars that can be used by cells.
- It is the organelle where photosynthesis takes place.
- It is only found in plant cells.
Mitochondria
- Mitochondria perform cellular respiration, the process of breaking down nutrients into energy for the cell.
- It is found in both plant and animal cells.
- It is known as the "powerhouse" of the cell.
Golgi Apparatus
- The Golgi apparatus converts combinations of molecules into new, more complex molecules.
- It then sends these molecules out of the cell or stores them.
- It is found in both plant and animal cells.
Smooth Endoplasmic Reticulum (E.R.)
- The smooth E.R. is an organelle attached to the nucleus that is involved in the creation and storage of lipids.
- It is found in both plant and animal cells.
- It looks like a group of tubes.
Rough Endoplasmic Reticulum (E.R.)
- The rough E.R. works with ribosomes attached to it to help synthesize and package proteins.
- It is found in both plant and animal cells.
- It looks like sheets of bumpy membranes attached to the nucleus.
Vacuole
- A vacuole is a storage bubble that stores food and nutrients that the cell needs to survive.
- They are found in both plant and animal cells but are larger in plant cells.
Ribosomes
- Ribosomes are small organelles that build long chains of amino acids for the cell.
- They are found in both plant and animal cells.
- They are known as the "protein builders" of the cell.
Peroxisome
- Peroxisomes digest nutrients and break down toxic materials.
- They are found in both plant and animal cells.
- They have digestive enzymes in their membranes to digest nutrients like amino acids, cholesterol, and fatty acids.
Lysosome
- Lysosomes help digest and break down food in the cell with the help of enzymes.
- They are only found in animal cells.
Microtubules
- Microtubules provide structure to the cell and help with cell division.
- They are only found in animal cells.
Centrioles
- Centrioles help the cell divide during mitosis and meiosis.
- They are only found in animal cells.
- They are made up of multiple microtubules.
Differences Between Plant and Animal cells:
- Plant cells have cell walls, animal cells do not.
- Plant cells have larger vacuoles than animal cells.
- Animal cells have centrioles, plant cells don’t.
