What is the job of the endoplasmic reticulum in a plant cell?
What is the job of the endoplasmic reticulum in a plant cell?
Endoplasmic reticulum (ER), in biology, a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells and serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins .
What does the endoplasmic reticulum do quizlet?
endoplasmic reticulum- A system of membranes that is found in a cell’s cytoplasm and that assists in the production, processing, and transport of proteins and in the production of lipids.
What are the 2 functions of the endoplasmic reticulum?
The ER is the largest organelle in the cell and is a major site of protein synthesis and transport, protein folding, lipid and steroid synthesis, carbohydrate metabolism and calcium storage [1–7].
What does the endoplasmic reticulum do simple definition?
Endoplasmic reticulum (ER) is a cellular organelle. It is the transport network for molecules going to specific places, as compared to molecules that float freely in the cytoplasm. The endoplasmic reticulum is in cells that have a nucleus: in eukaryote cells but not in prokaryote cells.
Why is endoplasmic reticulum important?
In some cells SER is responsible for transmission of impulses, e.g muscle cells, nerve cells. It also plays an important role in transport of materials from one part of the cell to the other. Endoplasmic reticulum also provides mechanical support to the cell so that its shape is maintained.
What is the function and structure of chloroplast?
Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so, they sustain life on Earth. Chloroplasts also provide diverse metabolic activities for plant cells, including the synthesis of fatty acids, membrane lipids.
What is photosynthesis kid definition?
Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas. Chlorophyll is a substance in all green plants, especially in the leaves. Plants take in water from the soil and carbon dioxide from the air.
What is photosynthesis class 7th?
Class 7 Biology Nutrition in Plants. Photosynthesis. Photosynthesis. The process by which plants make their own food in the presence of sunlight, carbon-dioxide present in air, water, minerals and chlorophyll present in leaves is termed as photosynthesis.
How did photosynthesis get its name?
This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek phōs (φῶς), “light”, and sunthesis (σύνθεσις), “putting together”. In most cases, oxygen is also released as a waste product.
What is the importance of photosynthesis Class 7?
Photosynthesis helps to maintain a balance between oxygen and carbon dioxide in the atmosphere as it absorbs carbon dioxide and release oxygen. Sunlight is necessary for photosynthesis. Thus sun is the ultimate source of energy for all living organism. Our earth is the unique planet, where photosynthesis takes place.
