Basic 1
What are types of organisms?
Single-cell / Unicellular
Multi-cell / Multicellular
What are the 2 ways that they reproduce?
Cell division/ Binary fission and Budding
Give an example of an animal cell.
Too many to list
What are the parts of cells that can be found in ALL plant cells?
Nucleus, Cell membrane, Cytoplasm and Cell Wall
What are cells?
There are the simplest building blocks of life.
Why are there different shapes of cells?
It is to perform specific tasks.
Eg. Elongated root cell to have more surface area to absorb water.
What can be found in an animal cell?
Nucleus, Cell membrane, Cytoplasm
What is the function of the chloroplast?
It contains chlorophyll to trap sunlight needed for photosynthesis.
Given 2 examples of a unicellular organism.
Bacteria, Yeast, Paramecium, Amoeba, Euglena
Why are the 2 reasons that cell division is important for a multicellular organism?
To replace dead and/or damaged cells
For growth
What is the purpose of a Cell membrane?
To control the movement of substances from entering and exiting the cell.
What are the differences between a plant cell and an animal cell?
Presence of cell wall = regular and irregular shape
Presence of chloroplast
What is the purpose of cell division for a unicellular organism?
It is to ensure the survival and continuity/ to prevent extinction of its species.
What happen to the cells in our body when we grow bigger and/or taller?
It increases in numbers. (not in sizes)
Which animal cell does not have a nucleus? How does that help with the function of that cell?
Red blood cell. It allows the red blood cell to carry more substances.
Why will happen to an animal cell and a plant cell when they are placed in a Petri dish filled with water?
The animal cell will burst while the plant cell will be swollen.
