What characteristics did the charophyte algal ancestor of land plants evolve that allowed it to survive out of water?
Ans.:- The characters which make the Charophyte algal ancestor of land plant to survive on the land or out of water are:-
1. They have a special proteins on their sperm which is called as the sporopollenin. This protein protect the sperm from all type of the dessication.
2. The cell wall is also made up of cellulose. It has the proteins that are arranged in circle. So the compactness of cellwall increase.
3. They have the enzymes which are similar to the land plants , so these enzymes can be used in the similar way as that of land plants.
4. Sperm shape is similar to the land plant, they does not have flagella.

please chose the right answer Question 25 1 points The ancestor of land plants is thought to be related to charophytes, a type of green algae. Why might it be advantageous for charophytes to undergo sexual reproduction? a. Charophytes, like land plants, have plasmodesmata, which need to be generated by sexual reproduction, b. Sexual reproduction produces larger numbers of offspring in less time. c. They are multicellular when conditions are unfavorable, which favors sexual reproduction d. Sexual reproduction produces multicellular...

Bryophytes & Seedless vascular plants: Be able to define a true “plant” Know how plants differ from other photosynthetic organisms (green algae, cyanobacteria) Understand that land plants share a common ancestor with green algae Be familiar with the four stages in land plant evolution, and know that both bryophytes and seedless vascular plants arose in the first stage seedless vascular plants diversified and dominated the Earth in the second stage, during the Carboniferous Period (~350-300 MYA), when coal deposits were...
