Cell Basics
What is the basic unit of life?
What is the basic unit of life?
What is the reproduction method that involves only one parent?
Asexual reproduction.
What is the main function of the cell membrane?
To protect the cell and control what substances enter and leave the cell.
Name one organelle that is found in plant cells but not in animal cells.
Chloroplast.
What is the most abundant gas in Earth's atmosphere?
Nitrogen
Name the substance that makes up the cell's outer layer.
Cell membrane or plasma membrane.
Name two types of asexual reproduction.
Budding and binary fission.
Describe the role of chloroplasts in plant cells.
Chloroplasts convert sunlight into food for the plant through photosynthesis.
What is the main difference between plant and animal cell shapes?
Plant cells are generally rectangular, and animal cells are round or irregularly shaped.
Which planet is known as the "Red Planet"?
Mars.
What organelle is known as the "powerhouse of the cell"?
Mitochondria.
What type of reproduction involves two parents?
Sexual reproduction.
What process do cells use to convert glucose into energy?
Cellular respiration.
Explain how plant cells make their own food.
Through photosynthesis in the chloroplasts.
What is cytoplasm?
The jelly-like fluid inside the cell.
Describe the function of the nucleus.
It controls cell processes and contains DNA.
Explain the difference between sexual and asexual reproduction.
Sexual reproduction involves two parents and genetic mixing, while asexual reproduction involves one parent and produces genetically identical offspring.
Explain the importance of the cell wall in plant cells.
It provides structure, protection, and support to the plant cell.
Identify one similarity between plant and animal cells.
Both have a nucleus, cytoplasm, and a cell membrane.
What force keeps the planets in orbit around the sun?
Gravity.
Explain why cells are considered the building blocks of organisms.
They are the fundamental structural and functional units of all living organisms.
Give an example of an organism that reproduces asexually.
Bacteria, yeast, or hydras.
How do cells in multicellular organisms communicate with each other?
Through chemical signals.
Why do animal cells not require a cell wall?
Animal cells do not need a wall for structural support as they do not engage in photosynthesis and are not exposed to the same environmental conditions as plant cells.
What is the largest organ in the human body?
The skin
