Study These Flashcards
A

-‘male’ pine cone
-contains pollen/sperm
-little tiny corn cobs
-‘smoother’ sides in microscope images, ‘horns’ of cone curve upward
-spaces between each ‘horn’ filled with dots (pollen)

23
Q

Ovulate

Study These Flashcards
A

-‘female’ pine cone
-contain egg
-looks line a stereotypical pine cone
-‘spinier’ sides in microscope images, ‘horns’ of cone point outward
-each space between each horn contains large oval egg

24
Q

Angiosperm

Study These Flashcards
A

-flowering plants
-vascular
-have seeds

25
Stamen
-'male' part of flower -made up of anther ('fuzzy' top part, contains microspores/pollen) and filament ('stem', bottom part, holds anther to flower) -microscopic anther image provided looks like moth, a void in each 'wing' holds microspores, which look like dots
26
Microspore
-forms pollen -each pollen grain contains tweo sperm cells
27
Carpel
-pistil -'female' part of flower -only one, surrounded by stamen -stigma; top of carpel, kind of looks like dark colored, partially popped popcorn -style; 'stem' of carpel, where the pollen tube is created to allow pollen to reach egg -ovary; hidden behind style/filaments
28
Flower Ovary
-contains megasporocyte (egg) -microscopic image looks like weird blue Rorschach test -thick outer part is ovary wall -six curled 'arms' in inner part are ovules
