Answer:
The correct answer is option B, The gametophytes grow directly from the sporophyte
Explanation:
Conifers are gymnosperm which reproduce through the exposed seeds (seeds not included in fruits) found in the cones. The trees or plant on which these conifers grow are called sporophytes. In the sporophyte, the male and female gametes fuse together to form zygote which further develops into a seed. At the right time, these seeds get dispersed into wind and they grow into new plants known as sporophytes.
Answer:
A cladogram is a visual representation of the relationships between organisms and also shows how organisms evolved from common ancestors. <em><u>Points where organisms branch off are called </u></em><em><u>nodes </u></em><em><u>and these nodes branch off show the last common ancestor among the organisms.</u></em>After each node, the line moves forward, which indicates where the organisms diverge. This means at this point, the organisms evolved traits that separates them from the common ancestor.
Answer:
a. two chromosomes with two sister chromatids each.
Explanation:
A tetrad is two homologous chromosome each consisting of two sister chromatids to make up four(4) chromatids. They are produced from meiotic cell division.
It is true. Cell division is called MITOSIS.
