Organelles
Explain the function of a nucleus
Controls the cell
Jelly like substance that fills the cell, what is the organelle?
Cytoplasm
True or false: The head and tail of a sperm cell is a specialised feature
True
Unicellular organisms are made up of how many cells?
1
What 3 organs is the circulatory system made up of?
heart, veins and arteries
Explain the function of the mitochondria
Powerhouse: Creates energy for the cell
Controls what enters and leaves the cell, what is the organelle?
Cell membrane
What makes the head and tail unique from a regular cell?
Most body cells stay in one place and do their job; sperm are designed to travel and fertilize an egg. Other cells don't have a head or tail
Multicellular organisms are made up of how many cells
many different types of cells
Explain how the circulatory and respiratory system
work together to maintain the function of the
body.
DOUBLE POINTS
The circulatory and respiratory system work together to achieve homeostasis of oxygen levels in the body. This
means maintaining a constant level of oxygen. The respiratory system job is to puts oxygen into the blood stream
and then the circulatory system pumps that blood around the body.
Explain the function of a Chloroplast
Turns sunlight into energy (photosynthesis).
Modifies proteins and helps move them, what is the organelle?
Endoplasmic Reticulum
Explain how the tail helps it complete its job
allows the cell the move, helps it swim to the egg
Groups of identical cells that perform a specialised job are called what?
Tissues
what is the function of the circulatory system?
The heart’s function is to pump blood around the body. Its structure is four chambers, two that pump blood to the lungs and two that pump to the rest of the body. The veins are a series of tunnels throughout the body, its job is to take deoxygenated blood back to the heart. The arteries are also a series of tunnels but take oxygenated blood to the rest of the body.
Explain the function of the lysosome
Disposes of waste in the cell (the garbage man of the cell).
Stores water, nutrients, and waste, what is the organelle?
Vacuole
Explain how the head helps it complete its job
Head shape is pointy to help sperm penetrate the egg and help with reduce drag while swimming.
Organs are made up of what?
one or more different kinds of tissue
and perform one main function or job.
What are the similarities in the circulatory system?
The heart, veins and arteries all carry blood Veins and arteries are both tunnel-like structures They all work together
Explain the function of the ribosomes
They make proteins
It is a control system in the cell, what is the organelle?
Nucleus
Explain how the Mitochondria helps it complete its job.
provides the cell with a energy, helps ensure the cell reaches egg
Explain how the structure of the plant leaf cell helps it to function.
hint: What does plant cells have that animal cells don't?
The leaf cell has many chloroplasts inside of it. This is because the leaf cell job is to make energy through
photosynthesis. Chloroplasts are the organelle that does this; thus it is advantageous to have a lot.
What are the differences in the circulatory system?
Veins carry deoxygenated blood, arteries have oxygenated blood The heart is in control of how much blood Is pumped Arteries are thicker than veins
