How do some cells make food?

Chloroplasts are the food producers of the cell. The organelles are only found in plant cells and some protists such as algae. Animal cells do not have chloroplasts. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells.

How do cells make and break molecules?

Cells are expert recyclers. They disassemble large molecules into simpler building blocks and then use those building blocks to create the new components they require. The breaking down of complex organic molecules occurs via catabolic pathways and usually involves the release of energy.

What type of molecules do cells use for food?

Most of the energy that we use comes from molecules of glucose, a simple sugar. Food energy is chemical energy that animals (including humans) derive from their food through the process of cellular respiration.

What part of the cell makes proteins?

ribosomes
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

Are cells made up of molecules?

All cells are made from the same major classes of organic molecules: nucleic acids, proteins, carbohydrates, and lipids. Though they are small, cells have evolved into a vast variety of shapes and sizes. Together they form tissues that themselves form organs, and eventually entire organisms.

Do molecules make up cells?

Atoms make up molecules; molecules make up cells; cells make up tissues; and two or more kinds of tissues working together make an organ. An organ is a part of the body that performs a specialized physiologic function.

How do cells create proteins?

In order for a cell to manufacture these proteins, specific genes within its DNA must first be transcribed into molecules of mRNA; then, these transcripts must be translated into chains of amino acids, which later fold into fully functional proteins.
