What is the function of the organelle in the picture?

• To support the outside of the cell and block molecules

• To make glucose by doing photosynthesis

• To sort, modify and package proteins

• To detoxify the cell and break down fatty acids

Answer explanation

This is a picture of the chloroplast which is found in plants and does photosynthesis.

What is the function of the organelle found in this picture?

• To break down food particles, wastes and old organelles

• To control cellular activities like protein synthesis

• To make energy by the process of cellular respiration

• To store water, nutrients and wastes

Answer explanation

This organelle is the mitochondria. It is found in plants and animals and it makes ATP (energy)

The endoplasmic reticulum has two parts. The ​ (a)   ER has ribosomes attached to it. It is the site of protein and lipid synthesis. The ​ (b)   ER is responsible for detoxification.

• rough
• smooth

Answer explanation

The part of the ER that has ribosomes is called "rough" because of the ribosomes attached to it.

In protein synthesis, ribosomes make the proteins. Some of these ribosomes may be attached to the rough ER. The created proteins need to go to the golgi apparatus to be modified. What organelle transports the proteins?

• vesicle

• mitochondria

• peroxisome

• centriole

Answer explanation

Vesicles are tiny membrane-bound sacs that transport molecules around the cell.

Several organelles help remove toxins and clean the cell in different ways. ​ (a)   are full of enzymes that they use to clean the cell. ​ (b)   break down hydrogen peroxide and fatty acids. ​ (c)   is also responsible for detoxification.

• Lysosomes
• Peroxisomes
• The Smooth ER
• The Golgi apparatus

What are the 3 parts of cell theory?

Answer explanation

1. All living things are made of cells

2. Cell are the basic units of life

3. All cells come from other cells

Which organelle found in animal cells helps form the mitotic spindle to help with cell division?

• Vacuole

• Plasma membrane

• Lysosome

• Centrioles

Answer explanation

Centrioles are only found in animal cells. During cell division, they help organize and create the mitotic spindle.

Select all that apply: Which of the following cell parts would be found in a plant but NOT an animal?

• cytoplasm

• cell wall

• large central vacuole

• chloroplast

Answer explanation

Plants have a cell wall made of cellulose. Animals do not.

Plants have a large central vacuole that stores water. Animals may only have small, temporary vacuoles.

Plants have chloroplasts for photosynthesis. Animals do not.
