What are the three functions of the Golgi apparatus?
The Golgi apparatus is responsible for transporting, modifying, and packaging proteins and lipids into vesicles for delivery to targeted destinations. As the secretory proteins move through the Golgi apparatus, a number of chemical modifications may transpire.
What would happen to the life of cell if there was mitochondria?
Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration.
What will happen if ribosomes and Golgi apparatus are removed from the cell?
If there were no ribosomes in the cell then there would be no MRNA. b If there was no Golgi apparatus, the proteins would float around not knowing where to go. Other cells and organs in the body wouldn’t function properly because they didn’t receive the products from the Golgi.
What are the main differences between plant and animal cells?
Major structural differences between a plant and an animal cell include: Plant cells have a cell wall, but animals cells do not. Cell walls provide support and give shape to plants. Plant cells have chloroplasts, but animal cells do not.
What Colour are lysosomes?
purple
Why are lysosomes absent in plant cells?
Lysosomes are not needed in plant cells because they have cell walls that are tough enough to keep the large/foreign substances that lysosomes would usually digest out of the cell.
Which cells lysosomes are absent?
- The Red blood cells do not contain lysosomes, mitochondria, nucleus etc.
- The absence of cellular organelles help them to accommodate maximum space for haemoglobin and helps in carrying more oxygen.
- It also gives a distinctive bi-concave shape to these cells and also helps in diffusion.
In which organisms lysosomes are absent?
Lysosomes are absent in animal cells A) Erythrocytes B) Plasma cells C) Nerve cells D) Muscle cells
- Hint:Lysosomes are membrane bound fluid filled organelles containing various hydrolytic enzymes that can break down many types of biomolecules.
- Complete answer:
- Thus, the correct answer is option (A) Erythrocytes.
Do plant cells have rough ER?
There are two types of endoplasmic reticulum: rough endoplasmic reticulum (rough ER) and smooth endoplasmic reticulum (smooth ER). Both types are present in plant and animal cells. The two types of ER often appear as if separate, but they are sub-compartments of the same organelle.
What is special about a plant cell?
Plant cells are the basic unit of life in organisms of the kingdom Plantae. They are eukaryotic cells, which have a true nucleus along with specialized structures called organelles that carry out different functions. Plant cells have special organelles called chloroplasts, which create sugars via photosynthesis.
Do plant cells have a Centriole?
Centrioles are found as single structures in cilia and flagella in animal cells and some lower plant cells. Centrioles are absent from the cells of higher plants but normal mitosis takes place and with satisfactory results.
