Animal And Plant Cell Structure And Organelles (diffs) Flashcards
What does the nucleus contain and control?
Contains DNA and controls the activities of the cell
The nucleus is often referred to as the control center of the cell.
Where do chemical reactions occur in a cell?
Cytoplasm
The cytoplasm is a gel-like substance that fills the cell and holds the organelles.
What is the function of the cell membrane?
Controls what goes in and out of the cell
The cell membrane is selectively permeable, allowing certain substances to pass while blocking others.
What do ribosomes make?
Proteins
Ribosomes can be found free-floating in the cytoplasm or attached to the endoplasmic reticulum.
Where does respiration occur and energy is released from glucose?
Mitochondria
Mitochondria are often called the powerhouse of the cell due to their role in energy production.
What does the vacuole contain and what is its function in plant cells?
Contains sap which maintains pressure within the plant cell, provides support for the growing plant and stores waste materials
Vacuoles are larger in plant cells compared to animal cells.
What is the function of chloroplasts?
Contains chlorophyll which converts light energy of the Sun into sugars that can be used by cells
Chloroplasts are the site of photosynthesis and give plants their green color.
What is the role of the cell wall?
Maintains cell shape, provides support for the plant, prevents cells from bursting
The cell wall is made of cellulose and is rigid compared to the cell membrane.
Fill in the blank: The _______ contains DNA and controls the activities of the cell.
nucleus
True or False: Ribosomes are involved in the process of respiration.
False
Ribosomes are primarily involved in protein synthesis, while respiration occurs in mitochondria.
Fill in the blank: The _______ is responsible for converting light energy into sugars.
chloroplast
