Why can a large seed be
planted deeper in the ground
than a small seed?

Answer:
If a small seed was planted too deeply in
the ground it would use up its food store
(in the cotyledon) before the first green
leaves appeared.

Nectary contains nectar to feed insects

W. McConnell 2004 Kinross High School

8..

What is the definition of fertilisation?

Answer:

Joining together the male and female
gamete.
W. McConnell 2004 Kinross High School

9..

What is meant by pollination in a
flowering plant?
Answer:

?

The process by which pollen
grains travel from anther to
stigma.

W. McConnell 2004 Kinross High School

10..
What is the difference between self
pollination and cross pollination?
a) Self Pollination means Pollen is transferred from anther to stigma of
the same flower.
b) Cross pollination means -

Pollen is transferred from anther to stigma of a
different flower.
W. McConnell 2004 Kinross High School

11..
What is the difference between wind
pollination and insect pollination?
a) Wind Pollination means Pollen grains are transferred by the wind.
b) Insect pollination means Pollen grains are transferred by insects.

Why can a large seed be
planted deeper in the ground
than a small seed?

Answer:
If a small seed was planted too deeply in
the ground it would use up its food store

Why can a large seed be
planted deeper in the ground
than a small seed?

Answer:
If a small seed was planted too deeply in
the ground it would use up its food store

Why can a large seed be
planted deeper in the ground
than a small seed?

Answer:
If a small seed was planted too deeply in
the ground it would use up its food store
(in the cotyledon) before the first green
leaves appeared.

What is meant by pollination in a
flowering plant?
Answer:

?

The process by which pollen
grains travel from anther to
stigma.

W. McConnell 2004 Kinross High School

10..
What is the difference between self
pollination and cross pollination?
a) Self Pollination means Pollen is transferred from anther to stigma of
the same flower.

Pollen is transferred from anther to stigma of a
different flower.
W. McConnell 2004 Kinross High School

11..
What is the difference between wind
pollination and insect pollination?
a) Wind Pollination means Pollen grains are transferred by the wind.

Why can a large seed be
planted deeper in the ground
than a small seed?

Answer:
If a small seed was planted too deeply in
the ground it would use up its food store
(in the cotyledon) before the first green
leaves appeared.
