What are unicellular organisms?	Unicellular organisms are organisms made up of only one cell.
What are organelles? Image: Flashcard 7 (binary/octet-stream)	Organelles are even smaller particles (structures) within the cell that act like small organs. Image: Flashcard 7 (binary/octet-stream)
Name 5 organelles found in animal cells.	1. Nucleus 2. Mitochondria 3. Lysosomes 4. Ribosomes 5. Endoplasmic Reticulum
What is mitochondria? Image: Flashcard 9 (binary/octet-stream)	The powerhouses of the cell that release energy from food. Image: Flashcard 9 (binary/octet-stream)
What is a nucleus?	The nucleus is the main organelle which has control over all movements of the cell.
What are ribosomes? Image: Flahcard 11 (binary/octet-stream)	Ribosomes are microscopic 'factories' that produce proteins used for the growth and repair of the cell. Image: Flahcard 11 (binary/octet-stream)
What are lysosomes?	Lysosomes are the garbage disposal units that get rid of waste from the cell.
What are endoplasmic reticulum? Image: Flashcard 13 (binary/octet-stream)	Endoplasmic reticulum form pathways that allow materials to move easily through the cell. Image: Flashcard 13 (binary/octet-stream)
What is a cell membrane?	The cell membrane is the 'skin' that holds the cell together.
What is a vacuole? Image: Flashcard 15 (binary/octet-stream)	A vacuole holds water and chemicals that are carried around the cell. Image: Flashcard 15 (binary/octet-stream)
What is a cytoplasm?	The water and jelly-like mixture that makes up the cell and holds smaller organelles in it.
What are chloroplasts? Image: Flashcard 17 (binary/octet-stream)	Chloroplasts are organelles holding chlorophyll used in the process of photosynthesis. Image: Flashcard 17 (binary/octet-stream)
What is a cell wall?	The cell wall is the skeleton-like outside of a cell.
Which organelles/parts of a cell are only found in plant cells and not animal cells? Image: Flashcard 19 (binary/octet-stream)	Chloroplasts and the cell wall. Image: Flashcard 19 (binary/octet-stream)
Describe the steps of photosynthesis.	1. Plant takes in carbon dioxide 2. Uses sunlight, water, carbon dioxide and chlorophyll to make its food. 3. Produces oxygen and glucose.
In which way is a fungal cell similar to a animal cell? Image: Flashcard 21 (binary/octet-stream)	A fungal cell has a similar inner structure to an animal cell. Image: Flashcard 21 (binary/octet-stream)
In which way is a fungal cell similar to a plant cell?	A fungal cell has a cell wall like a plant cell (however made of different chemicals).
