Plant Diversity & Anatomy

Moss antheridia (male)

Moss archegonia (female)

Moss protonema (juvenile stage of the haploid gametophyte)

fern prothallus (haploid gametophyte phase in a fern's life cycle that grows from a spore)

young fern sporophyte (developing diploid plant embryo that grows directly out of the haploid gametophyte)

pine ovulate cones (female w/ eggs)

pine staminate cones (male; packet w/ dots = pollen grain that produces sperm)

Is the large, green flat surface gametophyte or sporophyte? Diploid or haploid

Dicot leaf

Is this a root, stem, or leaf? Monocot or dicot?

Monocot leaf

What is this?

Primary growth in a root

What is this?

Primary growth in a stem tip/shoot

Which ovary position is this?

Hypogynous (stamens and other floral parts situated below the carpels)

Which ovary position is this?

Perigynous (stamens and other floral parts at the same level as the carpels)

Which ovary position is this?

Epigynous (ovary enclosed in the receptacle, with the stamens and other floral parts situated above)

What kind of fruit is this?

Simple fruit (develops from single carpel of one flower); examples: cherries, peaches, plums, olives, apples, pears, tomatoes, bananas, grapes, blueberries

What kind of fruit is this?

Aggregate fruit (develops from many separate carpels of one flower); examples: raspberries, blackberries, strawberries, and loganberries

What kind of fruit is this?

Multiple fruit (develops from many carpels of the many flowers that form an inflorescence); examples: pineapples, figs, mulberries, breadfruit, and Osage oranges

What kind of fruit is this?

Accessory fruit (develops largely from tissues other than the ovary); examples: strawberries (receptacle), apples (hypanthium/stem), figs (receptacle), and pears

Difference in monocot & eudicot embryos?

Monocot: one cotyledon

Eudicot: two cotyledons

Difference in monocot & eudicot leaf venation?

Monocot: Parallel

Eudicot: Netlike

Difference in monocot & eudicot stem?

Monocot: vascular tissue scattered

Eudicot: vascular tissue arranged in ring

Difference in monocot & eudicot roots?

Monocot: fibrous (no main root)

Eudicot: taproot (main root)

Difference in monocot & eudicot pollen?

Monocot: pollen grain with 1 opening

Eudicot: pollen grain with 3 openings

Difference in monocot & eudicot flowers?

Monocot: floral organs usually in multiples of 3

Eudicot: floral organs usually in multiples of 4 or 5
