- _______________are male flower parts that produce pollen that contain sperm
- _______________are female flower parts that produce ovules that contain egg
Male gametophytes = pollen grains, are formed in the microsporangia (pollen sacs)
embryo sac = female gametophyte and is formed within an ovule.
Key: pollen embryo sac germination double fertilization pollination pollen tube Embryo seed fruit dispersal endosperm

Union of 1 sperm nuclei with an egg & 1 sperm nuclei with 2 polar nuclei is ________ _______________
Zygote (fertilized egg) becomes the plant _________ & fertilized 2 polar nuclei become__________
Ripened ovule develop into _________________;
Ripened ovary becomes _________________
_________________ is beginning seed growth as the embryo grows a root and stem.
Signals for germination to start may be water and temperature.
Fruits house and protect seeds, help seed __________ & may be moved by wind, water, animals
ROOTS STEMS AND LEAVES
Plants have 2 systems: shoot and root. Stems, leaves, and fruit and flowers are part of the _______________system. Roots form the_________ system.
All reproductive and vegetative structures contain 3 types of tissue: dermal, ground, vascular
_________ tissue on outside __________ tissue, and _______________tissue (xylem and phloem).
Roots
1. List functions of roots._________________________ _______________________
2. (Monocot /Dicot) have taproots; (Monocot /Dicot ) have fibrous roots.
3. Label major root zones: Root cap; zone of cell division; zone of elongation, zone of maturation
| C _________________ is the meristem where cells divide rapidly D _________________ protects the growing root B _________________ is where cells increase in length A ________________ cells become mature example root hairs grow out of epidermis |
4. (Primary / Secondary) growth increase plant length of the plant; but
(Primary / Secondary) growth increases diameter/width.
5. Features of roots:
______ _____________ extend from mature root epidermis and increase surface area for water and mineral absorption.
Mycorrhizae are a mutualism of ____________ with plant roots: Plants supply food to fungii and fungi increase uptake of water and minerals for plants.
Root nodules of legumes contain ____________________ bacteria which convert nitrogen gas in the air into a form that plants can absorb in roots. Nitrogen fixation is essential for life to go on earth.

6..root x section monocots & dicots. all roots have epidermis, cortex, endodermis, vascular tissue
___________________ outermost cells protect the root and absorb water and minerals
___________________ cells used for food storage
___________________ single layer of cells between cortex and vascular cylinder of xylem and phloem.
___________________ tissue composed of xylem that moves water and minerals and phloem used is to move nutrients ( sugar sap). How are xylem and phloem arranged in a monocot? ___________
What is the shape of the xylem in a dicot? _______________________(Notice phloem around)
