Animal Cell
What is the function of the nucleus?
The nucleus controls the cells activities. It contains genetic material
What is the function of the cell wall?
The cell wall strengthens and supports the plant.
Define a cell, and give 1 example
The smallest unit of life e.g. a muscle cell.
What are the 4 properties of water?
Adhesion, Cohesion, Surface Tension and High specific heat capacity
Name at least 3 examples of food that contain carbohydrates
Bread, sweets, vegetables, fruits, pasta, rice, etc.
What is the function of the CELL MEMBRANE
The cell membrane controls the movement of substances in and out of the cell.
What is the function of the CHLOROPLAST
The chloroplasts contains the green pigment chlorophyll.
Chlorophyll absorbs light for photosynthesis.
Define an organ, and give 1 example
A group of tissues in the same place with the same role e.g. the heart.
Define cohesion
interaction of water molecules
Name at least 3 examples of food that contain protein
Meat, chicken, fish, cottage cheese, eggs, etc
What is the function of the CYTOPLASM
This is where many of the chemical reactions happen.
The cytoplasm contains dissolved nutrients and salts.
What is the function of the VACUOLE
The vacuole helps keep the plant cell turgid.
It is filled with cell water, nutrients and waste
List at least 3 types of animal tissues
muscle, nervous, epithelial, bone, blood, adipose, connective, cartilage
How is the process of changing the state of water from solid to gas called?
sublimation
Name at least 3 examples of food that contain lipids

What is the function of the RIBOSOME
Ribosomes synthesize all the proteins in the cell.
Energy production
What does the ‘levels of organization’ mean?
Levels of organization explain how living things are built - from the smallest parts (cells) to the biggest (organism)
What are the 4 main elements (atoms) of the human body?
Oxygen, carbon, hydrogen, nitrogen
Define the term "organic molecule"
Organic molecule - molecule which contains carbon
What is the function of the CENTRIOLES
The centrioles aid cell division.
They maintain cell structure and intracellular transport systems.
What is the diiference between plant and animal cell?
Plant cell has chloroplasts and cell wall, while animal cell does not. Also plant cell has a large vacuole, while animal cell has a small vacuole or none.
What is the correct order for the levels of organization?
Cell > tissue > organ > organ system > organism
What is the function of iron in the human body?
Iron is a part of haemoglobin, it plays a role in blood transport
What are the functions of carbohydrates, proteins and lipids in the human body?
Carbohydrates - provide quick energy
Protein - growth and repair
Lipids - Used for energy storage
