Cell Organelles

Front

What is the site of photosynthesis in plant cells?

Back

Chloroplast - the organelle that contains chlorophyll and is responsible for converting light energy into chemical energy through photosynthesis.

Front

What is the 'substance' of the cell where many chemical reactions occur?

Back

Cytoplasm - the jelly-like fluid inside the cell that holds organelles and is the site for many metabolic processes.

Front

What is the most important organelle in cell transport?

Back

Cell membrane - the structure that regulates what enters and exits the cell, maintaining homeostasis.

Front

What do the brown structures in a cell membrane represent?

Back

Carrier Proteins - proteins that facilitate the transport of substances across the cell membrane.

Front

What is the rigid, nonliving support structure made of cellulose in plant cells?

Back

Cell wall - a protective layer that provides structural support and shape to the cell.

Front

What organelle is responsible for energy production in cells?

Back

Mitochondria - known as the powerhouse of the cell, it converts nutrients into energy (ATP) through cellular respiration.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes - the organelles that synthesize proteins by translating messenger RNA.

Front

What is the role of the endoplasmic reticulum (E.R.)?

Back

Endoplasmic Reticulum - a network of membranes involved in protein and lipid synthesis; it comes in two forms: rough (with ribosomes) and smooth (without ribosomes).

Front

What is the function of the nucleus in a cell?

Back

Nucleus - the organelle that houses the cell's genetic material (DNA) and controls cellular activities.

Front

What is the role of lysosomes in a cell?

Back

Lysosomes - organelles that contain digestive enzymes to break down waste materials and cellular debris.
