Answer:
Parenchyma is the most simple and specialized tissue which is concerned mainly with the vegetative activities of the plant. The cells are isodiametric with well-developed intercellular spaces, vacuolated cytoplasm and cellulosic cell wall.
Collenchyma is the tissue of the primary body. The cells of the tissue contain protoplasm and are living without intercellular spaces. The cell wall articulate at the corners and are made up of cellulose, hemicellulose, and pectin.
Sclerenchyma is the thick-walled cell tissue. In the beginning, the cell is living and have protoplasm, but due to deposition of impermeable secondary board lignin, they become dead thick and hard.
Answer:
the organism reproduces asexually
Explanation:
it only needs itself and it uses cell fission
Answer:
A decompositon reaction is a reaction that takes place when one reactant breaks down into two or more simpler substances. The decomposition reaction can be represented by the general equation: AB → A + B. Most of the decomposition reactions require an input of energy in the form of heat, light or electricity
Explanation:
Acceleration is the rate at which velocity changes; here we are told the speed increases by 9.8m/s for each second of travel
assuming the object starts at rest, the object has a speed of 9.8m/s after one second, and a speed of 19.6m/s after two
mathematically, we write
v= at
where v is the velocity, a is the acceleration and t is the time of travel
so v= at = 9.8m/s/s x 2s = 19.6m/s
