Centrosomes and lysosomes are found in animal cells, but do not exist within plant cells.

The lysosomes are the animal cell’s “garbage disposal”, while in plant cells the same function takes place in vacuoles.

Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells.

The cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the cell.

The chloroplasts, found in plant cells, contain a green pigment called chlorophyll, which captures the light energy that drives the reactions of plant photosynthesis.

The central vacuole plays a key role in regulating a plant cell’s concentration of water in changing environmental conditions. follow me

Which electrons in an atom take part in chemical bonding and what are they called
miskamm [114]

Answer: The electrons in an atom that take part in chemical bonding are the electrons in the outermost shell and they are called valence electrons.

Explanation: An atom is composed of three particles: protons, neutrons and electrons. The protons and neutrons occupy the centrally located nucleus while the electrons are located in the empty space outside the nucleus. Electrons are distributed around the nucleus in paths called electron shells. The electrons in the outermost electron shells are called the valence electrons. The valence electrons are the electrons that participate in chemical bonding. During chemical bonding, the valence electrons are either transferred from one atom to another or the valence electrons are shared between two atoms. A type of chemical bonding in which there is a complete transfer of valence electrons from an atom of a metal to an atom of a non-metal so that can attain octet or duplet structure of noble gases is called electrovalent or ionic bonding. A type of chemical bonding in which there is sharing of electrons between two atoms of non-metals so that both can attain the octet or duplet structure of noble gases is called covalent bonding.
