Question

Which processes occur in a plant embryo before it pushes out of the soil? Check all that apply.

1.It uses food from the seed.
2.Its leaves open.
3.It produces its own food.
4.Its roots grow downward.
5.Its stem grows upward.

Answer 1

THe   plant  process   that  occur  in  a  plant  embryo  before  it  pushes  out  of  the   soil  are
it  uses  food  from  the   seed
its  root  grow   down wards
its  shoot  grow   upward
During  germination   seed  uses  food  which   is  stored in  the  cotyledon  of  the  seed.  Radicle  develop  into  root  while  hypocoytyl develop  into   shoot

Answer 2

Answer:

It uses food from the seed.

Its roots grow downward.

Its stem grows upward.

Explanation:

The cotyledons with is the seed store food which is used by the plant during germination. Within the seed lies a small plant called as embryo which germinates when the temperature, moisture, air and light conditions are adequate. The first stage of growth involves formation of primary root called radicle. In the second stage, the shoot emerges from the seed which has three main parts- a) the cotyledons, hypocotyl and epicotyl. The cotyledons are also called as seed leaves.  

Once the stem starts growing leaves come on it and hence it starts food production for itself through process of photosynthesis

Hence, the following options are correct

It uses food from the seed.

Its roots grow downward.

Its stem grows upward.
