Flowering plants produce male and female cells. The male cells are called pollen and the female cells are called ova. When a flowering plant is fertilized, it produces offspring in the form of seeds. However, not all plants reproduce flowers. Simpler plants, like mosses, lack these specialized structures.
Option C
This is an example of acquired mutation in which there is genetic transformation due to external factors such a change of temperature, pollution, radiation etc.
They have a range of important functions. Such functions include channeling or transporting molecules across the membrane.
Answer:
46 chromosomes
92 Chromatids
One DNA molecule
Explanation:
The interphase part of the cell cycle is divided into 3 sub-phases namely; G1 phase, S-phase and G2-phase
G2-Phase occurs when the cell grows more to make more proteins and organelles. This also when the cell reorganize its contents in preparation for mitosis. The number of chromosomes will therefore, remain the same but the DNA molecule will be one in preparation for mitosis where it can then divide into two
A
. Leaves were trapped between layers of sediment millions of years ago, causing the imprint
Explanation:
The only true explanation that perfectly describes the rock is that the leaves were trapped between the layers of sediment millions of years ago causing the imprint.
Leaf imprints are often referred to as trace fossils.
- Trace fossils points to the different life activities an organism must have been engaged in.
- When a leaf is trapped in a soft sediment between two layers, the compaction of the sediment can duplicate the form of leaf on beds.
- This gives a physical overview to the nature of leaf.
- Such an imprint did not grow, and cannot be attributed to metamorphic processes(option D).
- Option C is completely wrong
