  1. A ________________ is an edible plant part: leaves, roots, stems, or flowers.
  2. A __________ is angiosperm reproductive organ whose color, texture & nectar promote pollination. 
  3. A _____________ is a ripened ovary of a flower
  4. A  ____________ is a ripened ovule that contains embryo , food supply and seed coat..
  5. ______________ flower has all 4 parts ( sepals, petals, stamens, pistils).

______________ flower lacks  a part (sepals, petals, stamens, or pistils)

  • A flower with stamens and carpels is _____________;  Imperfect flower possesses only one sex ..

            An imperfect staminate flower has only ____________parts.

An imperfect pistillate flower has only _______________parts.

  • ______________ are the outermost leaf like structures of a flower.
  • _______________are conspicuous flower parts , may be colorful and fragrant to attract pollinators
  • _______________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.

A male gametophyte is ____________ grain.

Transfer of pollen from a flower anther to the stigma of a flower is ________________________

Female gametophyte is _____________________ formed within an ovule.

Sperm nuclei travel to the ovule by way of a _____________________.

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 systemsshoot 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? ___________
