Double fertilization-plants with seeds (flowering plants), two male gametes joining with female gametophyte
Gametophyte generation-both (haploid, sexual stage stage-gametophyte, and the diploid stage that produces spores – sporophyte)
Endosperm formed-plants with seed because it is a tissue formed inside the seed which surrounds the embryo and provides nutrition
Mitosis-both (mitosis occurres in spores)
Spores develop into gametophytes-both but, in seedless plants sporophyte produces spores that will develop into a new organism (multicellular gametophyte) using mitosis, while spores of seed plants are produced internally and develop into more complex structures.
Answer:
b, diploid.
Explanation:
Mitosis produces two diploid somatic cells, genetically identical to each other and the parent cell.
Answer:
- False
- True
- True
- False
- False
- True
Explanation:
A hypothesis is a supposition draw from data to carry an investigation or an argumentation.
1. The onion cells I looked at have a nucleus. False, even though the statement is true, is not a hypothesis because is not a supposition, it is rather an observation.
2. All onion cells have a nucleus. True, it is s a <u>valid hypothesis</u> because after the observation of 10 cells you draw a conclusion or supposition and affirm that all onion cells have a nucleus.
3. All cells have a nucleus. True, it is a<u> valid hypothesis</u> it contains a supposition derived from data observation
4. Some cells have a nucleus. False, the hypothesis is not valid because all of the observed cells contained nucleus not only some of them.
5. Only onion cells have a nucleus. False, after the observation of the different type of cells you see that they all had nucleus.
6. If I look at 10 skin cells from my hand, each one will have a nucleus. True, after the observation of different cells you can infer that if you look at your skin cells, they will have a nucleus.
