What organelle gives the cell its shape in plants and bacteria?

What organelle gives the cell its shape in plants and bacteria?

chloroplasts
Lysosomes are the digestive organelles of animal cells. Plant cells have a cell wall, chloroplasts, and a central vacuole. The plant cell wall, whose primary component is cellulose, protects the cell, provides structural support, and gives shape to the cell. Photosynthesis takes place in chloroplasts.

What cell produces a usable form of energy for the cell?

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

What is a rigid structure that gives protection support and shape to cells in plants algae fungi and bacteria?

Cell Wall. This is a rigid layer encompassing cells of bacteria, algae, fungi and plant cells. It determines cell shape and provides tensile strength, structural support and protection against osmotic pressure. Bacteria are either gram-positive or gram-negative – their cell walls are composed of a peptidoglycan.

What produces an unstable form of energy for the cell?

Phosphate groups are negatively charged and, thus, repel one another when they are arranged in a series, as they are in ADP and ATP. This repulsion makes the ADP and ATP molecules inherently unstable. The release of one or two phosphate groups from ATP, a process called dephosphorylation, releases energy.

What is the basic form of energy used by cells?

Adenosine 5′-triphosphate
Adenosine 5′-triphosphate, or ATP, is the most abundant energy carrier molecule in cells. This molecule is made of a nitrogen base (adenine), a ribose sugar, and three phosphate groups.

What part of the cell is the site of protein synthesis?

Ribosomes
Ribosomes are the sites in a cell in which protein synthesis takes place.
