Question

Explain what happens during primary growth.

Answer 1

Primary growth is in the vertical direction by the root and shoot apical meristem (embryonic tissue)

This includes 3 types of tissues:
protoderm: for the epidermis, roots hairs, cuticle, etc

ground meristem: ith and cortex, basically the inside of the sttem and root

vascular cambium: gives rise to vascular tissues

so the root grows when cells in the zone of cell division go under mitosis and the root elongates (the root cap protects the root when growing) The shoot (stem) grows by the 3 types of meristems and the shoot tip is protected by the terminal bud (the tip of the plant)

Answer 2

Thanks @alli14344 , hey @thomaster can you try to simplify this a little for me? I understand but I'm still just a tad bit confused, you're a genius so it wouldn't be a challenge.

Answer 3

np :)

Answer 4

Oke if you want it really simple: Primary growth extends the length of a plant both aboveground and belowground.

Do you need it further explained? like how the plant grows in length?

Answer 5

I just need to know what happens during primary growth.

Answer 6

The apical meristem (growing tip) on the roots and shoots of the plant, provide additional cells that enable growth in length. These growing tips consists of undifferentiated tissue where embryonic cell division takes place.

Thanks! :D
