Answer:
A. True
B. True
C. True
D. False
Explanation:
A. Plants in general are multicellular organisms, they are often referred to as eukaryotic autotrophs because they are make their own foods. They carry out photosynthesis, meaning the obtain their energy from sunlight.
B. Plants can be characterized by the presence of chloroplast, an organelle that helps in absorption of sunlight, because of the presence of green pigment called chlorophyll. There two major forms of chlorophyll in plants which are chlorophyll a and b.
C. Charophytes are a type of green algae, but several studies shows they have similar traits to land plants compared to other algae, making them have a common ancestor as plants. Some of the traits similarities to land plants compared to other algae are: they have similar enzymes, they have similar type of cell division, also their sperm is also similar to that of land plants.
D. Charophytes are not embryophytes. Embryophytes are also referred to as land plants, they are multicellular in nature, they include ferns and mosses. Charophytes are a type of green algae similar in traits embryophytes. Although embryophytes are a sister group to charophytes, they are not the same.

Answer
- Adaptation
- Genetic material
- Reproduce
Explanation:
In principle, viruses are considered as non living because they don't fulfill all eight characteristics of living organisms, i.e. RAREHOGG (reproduction, adaptation, response to stimuli, energy production, homeostasis, organization of cells, growth and development, and genetics). Specifically, they don't have energy metabolism, they don't grow, they don't respond to stimuli. However, they <u>can adapt the environment and reproduce.</u> But they do not reproduce independently, rather they need a host cell and use its machinery for reproduction. Based on these reasons, they are considered as living organisms.
Answer:
B
Explanation:
A zygote is the resulting cell from fertilization.
Fertilization occurs when the sperm (the male gamete/sex cell) fuses with the egg (the female gamete/sex cell). After they fuse, or fertilize, a cell forms that contains half of the DNA from the father (sperm) and the other half from the mother (egg). It has a complete set of DNA, and is considered a haploid cell.
It is not the structure that nourishes the fetus, an un-fertilized egg, or a ball of about 100 cells. Therefore, the correct answer is <u>B: a sperm fused with an egg.</u>
