Plant Cell Diagram


Use the above images in the table for reference
Explanation - Plants
Vacuole (light blue)
- Stores glucose and oxygen
- Like a pantry
- When cells can't photosynthesis, they use this storage
- More vacuole than in animal cells (because they store food and water in the vacuole)
Mitochondria (Red)
- Cellular respiration occurs here
- Makes/creates energy
- Called the 'powerhouse'
- Less energy required than animals (less mitochondria)
Nucleus (purple/pink)
- Contains many organelles
- One of the organelles is chromosome which contains DNA
- Surrounded by nuclear membrane
- Controls what the cell does and when
Cell Membrane (inner line outline)
- Inside the cell wall
Cell Wall (green outer outline)
- Makes the cell in a fixed shape
- Structural support
- Protection
Chloroplast (green)
- Contains tiny green pigments called chlorophyll
- Makes the plant green
- Traps sunlight
- Photosynthesis takes place
Chlorophyll
- Green pigments
- Absorbs energy from light
- That energy is used to convert carbon dioxide into carbohydrates
Explanation - Animals
Mitochondria (red)
- Makes energy
- The 'powerhouse'
- Cellular Respiration occurs here
- Greater energy required than plants (more mitochondria)
Nucleus (purple/pink)
- Contains DNA (like the plant one)
- Controls what the cell does and when
- Contains many organelles
- Contains genetic information (DNA, chromosones)
Vacuole (blue)
- Animals eat regularly to supply with food and energy
- Stores some glucose but doesn't need as much as plants since ^^ (point 1)
Cell Membrane (outline)
- Lets nutrients (oxygen and glucose - energy) in
- Takes wastes out

Prokaryotic and Eukaryotic Cells
Main difference: Prokaryotes don't have nucleus and Eukaryotes do have a nucleus.

About Cellular Respiration
- Process of converting oxygen and food into energy
- Takes place in Mitochondria
- Video on Photosynthesis and Respiration
Unicellular and Multicellular
Unicellular: Organisms made up of one cell
Multicellular: Organisms made up of multiple cells
The Five Kingdoms


Extra: Large Vacuole

Protoctista = present in some /
Fungi = absent x
Plantae = present /
Animalia = absent x
Why Photosynthesis is Important
Photosynthesis is very important to both animal and plant cells. Plants photosynthesis, therefore creating oxygen from the sunlight and waste products. Without plants doing this, there would only be one lot of oxygen that would eventually run out and everyone/everything will die out of lack of energy. Lots of animals also rely on plants as their food source so without it, the food they eat would not be giving them anything (nutrients, energy).
Why do Plants need to Respire and Photosynthesis?
Plants need to do both for them to survive and for others too. Plants cannot live without respiration because that is how they make energy (animals also use respiration but not photosynthesis). Photosynthesis is another way for them to create energy (since they do not eat manually like animals) but this also creates energy for animals since they are creating oxygen from waste products and sunlight.
Which Substances Recycle during Photosynthesis and Respiration?
Carbon Dioxide, Oxygen, Water and Glucose
- Carbon dioxide (and water) gets used in photosynthesis with plants to create oxygen and glucose
- Oxygen is used in respiration (with glucose) to create energy and carbon dioxide
- Water is water. It gets fed to animals and plants and then they pee it out
- Glucose is used in respiration (with oxygen) to create energy and carbon dioxide
Why Aren't Virus' Alive?
Viruses aren't alive because they aren't made of cells. They do not grow or make energy either.
