Common-Core Grade 7 - 7 Identifying functions of plant cell parts
The endoplasmic reticulum is an organelle that helps ribosomes build proteins.
Golgi apparatus assists in the processing and packaging of proteins and lipid molecules, particularly those destined for cell export.
Tonoplast is a membrane that surrounds the central vacuole.
Lysosomes are called suicidal bags as they hold digestive enzymes in an enclosed membrane.
The nucleus is a membrane-bound structure that is present only in eukaryotic cells.
In eukaryotes, ribosomes get their orders for protein synthesis from the nucleus, where portions of DNA (genes) are transcribed to make messenger RNAs (mRNAs). An mRNA travels to the ribosome, which uses the information it contains to build a protein with a specific amino acid sequence.
Lysosomes are called suicidal bags as they hold digestive enzymes in an enclosed membrane.
Chloroplasts are the organelle of photosynthesis. They capture light energy from the sun and use it with water and carbon dioxide to make food (sugar) for the plant.
cell wall is the outer, protective layer
Mitochondria's primary function is to produce energy through the process of oxidative phosphorylation. Besides this, it is responsible for regulating the metabolic activity of the cell. It also promotes cell multiplication and cell growth.
