Leaf Analysis

Submitted by riyjpatel on Tue, 07/09/2019 - 15:13

This leaf is freshly green. My leaf has a stem that attaches the leaf to the plant. The petiole (the stalks that joins a leaf to a stem) is extended into the leaf and divides equally into two. The leaf has a weird line going through the leaf like a bunch of scribbles making it seem as if an insect has left its trial on it. The leaf is very long and has a midrib through it. It also has a ton of veins. The structure of the leaf on the outside is very spiky. There’s a minor cut on the bottom of the leaf not going all the way to the stem but close enough. The leaf feels very smooth but can feel the veins the make the leaf. The bottom of the stem is very thick because its ripped off the plant. The stem gets thinner and thinner as it runs down the leaf. It has a small brown patch near the base of the leaf. The leaf is 18.5 cm long. The width of the leaf varies anywhere from 1-5cm wide. The leaf has parallel margins. It portrays a long line with spikes coming out in the center probably known as the midrib. Chlorophyll is definitely present in the leaf giving off the green color as it absorbs light energy.

Looking at a Leaf

Submitted by ifernandez on Tue, 07/09/2019 - 15:13

Not exactly sure what type of leaf it is. Its length is greater than its width.
The top side has a distinct white/yellow line that resembles some sort of outline,
however this white line outline does not appear on the bottom side of the leaf.
On a side note, the leaf's edge is not a smooth rounded one, but instead it's rather jagged.
From the stem the leaf begins to widen its shape until about two thumb lengths away,
and after that it beings to narrow until it reaches its full length at the tip of the
leaf a little over another thumb length away. In addition, the leaf is not very sturdy in structure,
instead it's flimsy and weak and feels like any applied force could rip it apart.
The measured length is 14.40 cm and the measured width is roughly 4.0 cm.
The stem which continues throughout the leaf has small white hairs on the bottom of the leaf.
There is a small cut on the left side of the leaf about 6.0 cm from the start of the stem.
There is also a small circle, which I believe is a tiny hole in the center of the leaf about 0.60 cm from the tip.
The right side of the leaf has 23 tips while the left side of the leaf only has 22 tips.
Also after letting the leaf's stem sit in water for a small period of time (almost 30 minutes?) the leaf is not as
flimsy as it was when received.

Leaf Observations

Specimen: One green leaf approximately 6.5 inches long. Has a elliptical shape with pointy ends. Has a serrated appearance on the edges. The width of where the stem was attached to the mother plant is about .25 inches across.
Interesting Features: There is a lighter green ribbon like structure across one vertical half of the leaf, on the right side. It almost appears as if someone drizzled the leaf with a lighter green paint. There appears to be two separate "tracks" of this lighter green. It looks to me like an insect was eating parts of the leaf and this is the track left by that. The tracks are minuscule in width. I would say they are 1/16 of an inch at most. I'd say one of them is about ten inches in length an the other is about 6. The ribbon like structures appear to be only on the surface of the leaf. On the back side of the leaf they are barely visible. On the left side of the leaf there is an odd shaped hole. There is a yellowing around the edge of this hole. It has the shape of a fidget spinner. There appear to be fine, hairlike structures on the stem of the leaf. The stem is more of a yellow green than the rest of the leaf. There are small almost shiny dots on the leaf that go away after it is washed.
The specimen is a serrated edged leaf. The leaf is approximately 155mm in length with an elliptical shape. One end has the base of the stem where the leaf was attached to the mother plant. The other end is pointed. At the widest part, the leaf measures about 50mm. The stem is about 5mm across. There appear to be 2 lighter green "tracks" on the leaf. They take on a drizzled appearance. Almost as if someone drizzled icing on the leaf. The widest part of these tracks measures approximately 2mm at the thinnest part the track measures less than .5mm. These tracks only appear on the right vertical half of the leaf. They only appear on the top surface of the leaf. The length of the tracks in total measure about 105mm and 145mm. On the left vertical half of the leaf there is an oddly shaped hole that has the shape of a fidget spinner. This hole has yellowing around the edges and is about 70mm up from the base of the stem.
