Plant Characteristics
3. All plants have 5 adaptations for
living on land:
1. Obtain water and
minerals from soil
~ root systems
2. Retain water by a
cuticle – water
proof layer on
leaves
4. 3. Transport material – thru cells and
vascular tissue
a. Vascular tissue – tissue that
transports water, nutrients and minerals
b. Plants that have vascular tissue are
called vascular plants
c. Vascular plants can grow tall
because of the support of vascular
tissue.
5. 4. A plant on land needs to support its
body
a. Leaves must be exposed to as much
sunlight as possible
b. Vascular tissue strengths and
supports large plant
5. Most do sexual reproduction with
fertilization of egg and sperm =
zygote
6. Complex Life cycle
1. Two stages (or generations): produce
different things for reproduction
Fertilization
produces a
zygote
Alternation of
Generation
7. Two stages
a. 1st
stage – Sporophyte – the plant produces
spores
- spores – tiny cells that can grow into new
gametophyte
b. 2nd
stage – Gametophyte – the plant produces
two types of sex cells (sperm and egg)
- egg + sperm = zygote = becomes a
sporophyte
- cycle starts over again
