Microtubules are hollow tubes of protein that maintain cell shape and permit movement of cell organelles.
Answer:
<em>The correct option is B) Plant development continues throughout the life of a plant.</em>
Explanation:
In plants, growth is considered to be continuous. Meristems ca be described as the embryonic cells in plants by which new organs of the plant are formed throughout their life. Meristems are undifferentiated cells which have the ability to develop into different plant organs. Hence, option B is correct.
Other options like option C is not correct because the plans do develop and their cells are able to differentiate.
Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) in the form of the mineral calcite. It most commonly forms in clear, warm, shallow marine waters. It is usually an organic sedimentary rock that forms from the accumulation of shell, coral, algal, and fecal debris.
The determination of the past arrangement of leaves from bare twig are
- Flower bud
- Lateral branching
- Lateral terminal bud
- Leaf scar
- Node
- Inter node
- Auxiliary buds
- Bud scale
- Terminal bud
<u>Explanation:</u>
Terminal bud: it is the large bud at the apex of the twig. Uses of the bud is to protect the dormant meristem.
Bud scale: a small modified leaf on outside of bud.
Auxiliary bud: It is found just above the each leaf scar. Not all twig will have a full complementary of auxiliary buds. They frequently gets damaged.
Lenticles: Opening in the bark that allows for gas exchange into and out of underlying living tissues.
Leaf scars: It is present at the stem for the triangular regions.
