Organelles
Define an organelle.
Organelles are structures within the cell that perform important functions. Each has a job to do.
True or False
The cell wall is NOT part of the animal cell.
TRUE
The cell wall is only in a plant cell.
When scientists examine a cell with a microscope, the outlines of plant cells are easily seen. Unfortunately, the outlines of an animal cell are harder to see. Explain why animals cells are harder to see than plant cells.
It is easier to see a plant cell because of the cell wall. Animal cells do not have the cell wall. They only have a cell membrane.
Name two things that are ONLY found in a plant cell.
Chloroplast and the Cell Wall
The lysosomes do what for the cell?
Lysosomes break down wast in a cell. It is the garbage man of the cell.
Which structure controls what enters and leaves the cell?
cell membrane
True of False
The cell wall regulates what enters and leaves the cell.
False
The cell membrane is the door that decides what gets in and out of the cell.
The cell wall is part of the plant cell.
It surrounds and protects the plant cell. It gives the cell its shape and helps the cells stick together.
If a scientists is looking at a plant cell through a microscope, how many vacuoles will that scientists see in a plant cell.
Plant cells have one HUGE VACUOLE.
Animal cells have smaller vacuoles and more of them.
Name the purpose for the Cell Wall.
The cell wall helps the cells stick to each other and gives it shape.
Explain what function ribosomes serve in the cell.
Ribosomes are the protein builders of the cell. Think of them as the cook of the cell.
Describe the functions of a nucleus.
The nucleus is the control center of the cell. It also contains all the genetic material of the cell.
True or False
Cytoplasm gives plants its green color and makes sugar for the plant to use and store through photosynthesis.
False.
Chloroplasts give plants its green color and makes sugar for the plant to use and store through photosynthesis.
When scientists watch the animal cell through a microscope, what will that scientist see the cell membrane doing for the cell?
A cell membrane is like a door. It decide what gets in and out of the cell. The cell membrane allows water and nutrients to pass into the cell. It also allows waste to pass OUT of the cell. It will stop some materials from coming inside and injuring the cell.
What do chloroplasts do for a plant cell?
Chloroplasts use the energy from the sunlight and work to combine carbon dioxide and water to produce sugar for the plant to use and to store.
This process is called photosynthesis!!!!
Explain the function of the mitochondria.
The mitochondria is the powerhouse of the cell. they act like a digestive system with takes in nutrients, breaks them down and creates energy for the cell.
Describe what the chloroplasts do.
Chloroplasts trap energy and change it into food for the cell. PHOTOSYNTHESIS takes place inside the chloroplasts.
True or False
The invention of the microscope made it possible for people to discover animals, skin and plants.
False.
Microscopes help people see plant and animal cells.
Through a microscope, the organelles look like they are floating. What is the material that they float in called?
Cytoplasm is a jelly-like substance that fills the cells.
What gives plants cells the green color?
Chloroplasts
What is the purpose of the Golgi?
Golgi means GO because proteins are going to be delivered tot he next stop. The Golgi apparatus takes in protein, changes it and then places it in shipping containers called vesicles. The Golgi apparatus also makes lysosomes, which are digestive enzymes.
Which organelle contains most of the cell's genetic material?
The nucleus contains most of the cell's genetic material.
True or false
The mitochondria helps the cell remove waste.
False
The mitochondria is the powerhouse of the cell. It releases the energy when the nucleus tells it to do it.
When scientists look through a microscope, what shape do the plant cell and the animal cell resemble or look like?
Where does photosynthesis take place in the cell?
The plant cell has chloroplast which uses photosynthesis to make sugar from carbon dioxide and water to make sugar to use and store.
Explain what the Endoplasmic Reticulum does for a cell.
The Endoplasmic Reticulum functions as a manufacturing and packaging system.
