Answer:
Like all organisms, plants detect and respond to stimuli in their environment. Their main response is to change how they grow. Plant responses are controlled by hormones. ... Plants also respond to daily and seasonal cycles and to disease.
Answer: d. alternation of multicellular generations
Explanation:
The gametophytic as well as the sporophytic generations are alternative in the life cycle of the multicellular plants. This can be seen among the land plants. This feature cannot be seen in the algal species as they are unicellular in nature. Thus cannot be seen in the relatives of charophyta algae.
Answer:
The correct answer is a. domain Eukarya.
Explanation:
Bacteria archaea and eukarya are considered as the three domains of life. Bacteria and eukarya lack a membrane-bound nucleus and other membrane bound organelle therefore they are considered in prokaryotes and organisms having membrane-bound nucleus comes under domain eukarya.
So the organism which have eukaryotic cell comes under domain eukarya. These organisms can be single cellular or multicellular and their genetic material is packed in a double membranous structure called the nucleus. So the correct answer is a. Eukarya.
Answer:
The correct answer is ''They are all vascular plants''.
Explanation:
Vascular plants or tracheophytes are those organisms of a more evolved plant nature, they are those that have leaves, stem and roots and that have a vascular system formed by conducting vessels. Ferns are pteridophytic vascular plants, they do not produce flowers or seeds and are mostly herbaceous. All those vascular plants that have seeds but do not have flowers are called gymnosperms. The seeds are not covered or protected by an ovary, so they appear visible on the leaves or other parts of the plant. Angiosperms are plants with flowers, whose seeds develop within the ovary, which grows and becomes fruit.
