Draw and Label an Animal Cell

Answer explanation

You are made up of many different animal cells. Generally all animal cells will contain these structures. You are more similar to animals than you may have realised!

Draw and Label a Plant Cell

Answer explanation

Did you know that Plants can make their own food? They do this through PHOTOSYNTHESIS!

Photosynthesis comes from the two latin words, photo and synthesis.

Photo = Light

Synthesis = To Make

So the name photosynthesis means, to make from light!. Cool Huh?

A plant cell has these things, but an animal cell does not.

• Cell Wall & Cytoplasm

• Cell Membrane & Nucleus

• Vacuole & Cytoplasm

• Cell Wall & Vacuole

Answer explanation

Animal cells do not have a cell wall to keep them strong. They also do not have vacuoles like plants do. As animal cells do not have chloroplasts that means they cannot make their own food through photosynthesis.

Can you imagine what a human with chloroplasts might look like? It isn't easy being green.

Animal cells have a nucleus, ________ and a cell membrane.

Answer explanation

Animal Cells contain a Nucleus, Cytoplasm and Cell Membrane. That cell membrane allows things to enter and exit the cell, but only some things! The cytoplasm is a jelly-like substance that is the site of chemical reactions.

Plants can produce sugar through photosynthesis. They have ________ which appear green because they contain chlorophyll.

Answer explanation

Chloroplasts are very interesting. I wonder what our world would look like if all creatures had them. Would we have a need to eat other creatures to survive? How might we have evolved differently?

DNA has four bases.

Match them with their pairs.

• C

• G
• A

• T

• G

• A

• T

• C

Answer explanation

Your DNA is unique. Unique means that nobody else has it. There is generally only one exception to this which are identical twins. They would share the exact same DNA! However, they can grow up to look different depending on things like environment.

Your DNA is unique to you! So just remember you are UNIQUE! Just like everyone else.

What is the primary function of the cell wall in plant cells?

• To control the entry and exit of substances

• To provide structural support and protection

• To perform photosynthesis

• To store nutrients

Answer explanation

Cell Walls help protect the plant Cell and give it shape. Think of it like a second membrane. This is usually made of cellulose, and gives plants its strong structure. This cellulose is so strong that we use it for different things! For example, paper that you write on, napkins, paper-towels and other paper products are all created through cellulose. We can also use it as waterproofing in clothes, and it is even used in some foods!

Which organelle is responsible for photosynthesis in plant cells?

• Vacuole

• Nucleus

• Chloroplast

• Cytoplasm

Answer explanation

Chloroplasts contain a green pigment called Chlorophyll. It is this pigment that allows photosynthesis to happen. Not all cells in a plant have this green pigment. For example, potatoes underground do not contain it. But the leafy part of the plant has lots!

What role does the nucleus play in a plant cell?

• It stores DNA and directs all cellular activities

• It assists in the process of photosynthesis

• It provides structural support to the cell

• It helps in the storage of nutrients

Answer explanation

Both animal and plant cells contain a nucleus. That means we both contain DNA, as this is where our genetic information is stored. Did you know that we are related to plants? Think of them like your long lost distant cousins. We evolved one way, they branched off another...

Organize these options into the right categories

Groups:

(a) Animal Cell & Plant Cell

,

(b) Plant Cell Only

• Cell Membrane

• Cytoplasm

• Vacuole

• Nucleus

• Chloroplast

• Cell Wall

Answer explanation

Some things between plants and animals are so similar we can't believe it. Robert Hooke looked at cork under his microscope and was so inspired by what he saw he wrote a whole book! Micrographia published in 1655 contained drawings of cells, never seen before! He named the little boxes cells, as they reminded him of what a prison cell looked like.
