5 Identify the following characteristics as either eudicot or monocot:

MONOCOTFlower parts in multiples of threes ,Scattered vascular bundles ,Secondary growth absent, Embryo with one cotyledon ,Pollen with sulcus and one pore ,Parallel venation of leaf veins

EUDICOTPollen with three apertures ,Embryo with two cotyledons ,Netted venation of leaf veins ,Flower parts in multiples of fours or fives,Secondary growth present ,Vascular bundles arranged in a ring

1.1 In vascular plants, is the specialized tissue that carries nutrients within the plants and is the tissue that carries water

The phloem carries nutrients

The xylem carries water

1.2 In plants, what are the basic dermal tissues? Epidermis

1.3 What is the basic function of meristematk tissue?

It undergoes mitosis to form the permanent tissues

1.4 Label the following phloem tissues with the correct type of function.

Parenchyma cells Companion cells Sieve tube members Sclerenchyma A. Provides conductionsieve tube, companion cells

B. Provides storage Parenchyma cells

C. Provides support --sclerenchyma cells

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
