Functions of a plant cell Flashcards
(8 cards)
What provides a rigid outer layer that protects the cell and gives it shape?
Cell Wall
The cell wall is a structural component found in plant cells, bacteria, fungi, and some protists, providing rigidity and support.
What is the function of the Cell Membrane?
Controls what enters and leaves the cell; acts as a selective barrier
The cell membrane is vital for maintaining homeostasis within the cell.
What does the Nucleus contain?
The cell’s DNA
The nucleus regulates cell activities such as growth and reproduction.
What is the cytoplasm?
Jelly-like fluid where most cell activities and chemical reactions happen
The cytoplasm holds organelles in place, facilitating cellular processes.
What do Chloroplasts contain and what is their primary function?
Contain chlorophyll and are the site of photosynthesis
Photosynthesis converts sunlight into food (glucose) for the plant.
What is the role of Mitochondria in the cell?
Produce energy by breaking down sugars during cellular respiration
Mitochondria are often referred to as the powerhouse of the cell.
What does the Large Central Vacuole store?
Water, nutrients, and waste
It helps maintain cell shape by keeping the cell turgid.
What is the function of Ribosomes?
Make proteins needed for the cell’s functions and growth
Ribosomes can be found floating freely in the cytoplasm or attached to the endoplasmic reticulum.
