A: Lesson Activity All about cells Althea was in Grade 7 at school and her teacher was telling them all about cells and although she found it interesting, she felt that she didn't really understand what the teacher was saying. She decided to tell her younger brother Angelo a story about cells to see how much she could remember about the lessons. This is what she said: "Did you know that every living thing is made of cells and that some tiny living things like bacteria are made up of only one cell but that human beings are made up of 75 trillion cells. Most cells have three main parts, but plant cells are a bit different to animal cells. I will draw them for you." A X- X₂ B
Component 4B
Q1. Which of the two cell diagrams A and B is a plant cell?
Q2. What is the name of the parts labelled X and Y in the two cells?
Q3. Are the cells in our heart the same as the cells in our brain? Why or why not?
Component 4C
Q1. What do the cells in the organisms of similar species have in common?
Q2. Name three essential functions of the human cell.
Q3. What are the structures inside the nucleus called and why are they so important?

Answers & Comments
Answer:
component 4b
1. Diagram B is a plant cell.
2. The parts labelled X and Y are the cell membrane and the cell wall, respectively.
Q3. Are the cells in our heart the same as the cells in our brain? Why or why not?
No, the cells in our heart are not the same as the cells in our brain. This is because the cells in our heart are specialized to pump blood throughout the body, while the cells in our brain are specialized to process and store information. The cells in our heart are also much larger than the cells in our brain.
Component 4c
1. Cells in the organisms of similar species have the same basic structure and components.
2. Three essential functions of the human cell are to provide energy, to store and process information, and to produce proteins.
3. The structures inside the nucleus are called chromosomes and they are so important because they contain the genetic information that determines the characteristics of the organism.
