Question

Consider a meal you ate recently. Using terminology from this lab, describe what you ate. You must discuss at least three different tissues and/or cell types. This may take some research. Here is an example that you cannot use: In my garlic mashed potatoes, the potatoes are comprised of parenchyma tissue, made up of parenchyma cells.

Answer 1

Hi,

Please find the below answer. Hope this will help you out.

I ate Bitter melon curry in my dinner which is not a favorite one for most of the people but it contains many nutritional values. So I will take that as an example for this answer.

Bitter gourd belongs to
Kingdom: Plantae
Order:   Cucurbitales
Family:   Cucurbitaceae
Genus:   Momordica
Species:   M. charantia

Anatomy is different in fruits, seeds and leaves.

The fruit has a tuberculate surface presenting numerous swellings.
The pericarp is characterized by five distinct tissues:

Epicarp – the cells are generally isodiametric with those close to the stomata being tangentially-elongated. The outer periclinal walls are covered by a thin cuticle; the underlying two-three layers present occasionally thickened walls.

Outer mesocarp – this tissue consists of a variable number of layers (5–7) with large isodiametric or radially-elongated cells, apparently devoid of cell sap, and a network of tinny intercellular spaces

Middle mesocarp – the cells are tangentially-elongated and thick-walled, often turgid with a watery cell sap and containing a small amount of starch. Numerous bicollateral vascular bundles occur throughout the middle mesocarp: they are either small and soft, or large and stiff, forming an anastomosing vein-like system arranged in a ring

Inner mesocarp – several layers of thin-walled cells, forming this tissue, present a huge amount of starch in comparison to the preceding layer. The cells are large with wide intercellular spaces. The inner layer bears stomata and delimits a cavity containing the seeds

Endocarp – this tissue, formed by very small, thin-walled and tangentially elongated cells, is thin and translucent.

The seeds are oblong with grooved margins and a sculptured surface. The seed-coat may be differentiated into five distinct layers, that are enclosed by the aril.

Epidermis – this tissue consists of a single layer of prismatic palisade cells. They are generally of equal height over the flat surface of the seed, increasing in height at the sculpturations. The radial walls are often uniformly thickened, nevertheless in some cases they have either straight or branched thickenings running from the inner to the outer tangential walls. The outer walls are thickened. A noteworthy feature is the presence of large starch grains in this layer

Hypodermis – this tissue is made up of four layers of small, isodiametric, tightly closed sclerenchymatized cells, without intercellular spaces. A huge amount of starch granules is evident

Sclerenchyma – this layer consists of exceedingly thick-walled cells. The walls are sinuous and the starch content is massive

Aerenchyma – many cell layers of spongy parenchyma, differing greatly in size and shape, make up this layer. The cells of the outer layers are usually small and frequently sclerenchymatized. Underneath these small cells are one or more layers of either large or small thin-walled cells having very large intercellular spaces. The vascular bundles are imbedded in this layer at the flattened surface of the seed.

Chlorenchyma – a single layer of small, polygonal, and inconspicuous thin-walled parenchyma cells, containing chlorophyll, forms the inner tissue
